When you need to gather confidential information and relay it to someone who is far away, without making the people around you aware, or when you need to receive instructions from outside in the same discreet fashion, you might certainly use a little help from technology.

In situations of different kinds, which may range from an important meeting to a police operation, from a show or concert, where the leading actor may forget a few lines from his part, to an intelligence gathering in a case of corporate espionage or struggle against crime, a valuable help can certainly come by using an invisible earpiece.

Invisible earphones are placed inside the ear canal of their wearer, and thanks to a microscopic antenna, they are able to communicate via Bluetooth with an equally small transceiver device, which can be concealed inside the pendant hanging from a necklace, or inside a wristwatch. This transceiver can also house a SIM card just like the ones we use on our mobile phones, in order to be able to send and receive its signal (and its intelligence) towards someone who might be hiding even on the other side of the world.

In this way, the wearer of the secret earpiece will be able to receive instructions on the steps to take, based on the information that it gathers invisibly and that are transmitted through the Bluetooth connection. By doing this, the remote counterpart will receive information in real time, and interact with the person carrying out the operation, sending him immediate instructions which will ensure the best possible outcome of the entire job.

If telephone wiretapping is becoming a more difficult tool to use, at least in Italy, law enforcement can certainly not stop their investigation work, and in order to fight crime, in some cases they must resort to a more cumbersome and dangerous method, that is, for example, trying to infiltrate a criminal organization or a terrorist cell, in order to try and gather in first person information that might be collected with listening bugs.

In order to carry out this kind of operations, one of the most useful instruments that surveillance technology can provide is certainly an invisible earpiece, that is, a miniaturized transmitter that, once placed inside the ear canal, can be used to listen to what is happening around its wearer, and to send him information and instructions from a remote location, in order to guide him in his intelligence gathering operation.

Invisible earpieces conceal, in their tiny size, a micro transmitter which can be connected via Bluetooth to a radio transmitting or GSM watch, that is, something that looks like your ordinary wristwatch but on the inside contains a radio transmitter or a SIM card just like the ones we use on mobile phones. Through this set, the information gathered through the earpiece can be sent via radio to a listener hidden somewhere within a range of a couple of kilometers, or by using the GSM phone network, it can be sent to any corner of the world towards a preset phone number, starting the transmission operation with the simple click of a button.

The Japanese giant Yamaha has just announced the commercial launch of its first micro earpieces, to be placed inside the ear, designed for the music players market, but with an eye that looks to the professional market as well.

For Yamaha, it is the first approach towards this kind of market, and the step is taken with three different models of micro earpieces: the basic model EPH-20 has a diameter of approximately 1.1 centimeters, while other models EPH-30 and EPH-50 have a diameter of respectively 9 and 13 millimeters.

Their retail price can range from 20 dollars for EPH-20, up to 100 dollars that you would need to bring home a EPH-50 model, ideal also for a professional use, thanks to its sturdiness and to its 0.25” jack adaptor, which would allow you to use it also on your home stereo set.

Of course, these models cater to a clientele which is mostly using the earphones for leisure or for listening to music on the go. In spite of the good quality, these earpieces could not possible be used in our specific field, as audio surveillance operations or intelligence gathering require that the person carrying them out use a wireless invisible earpiece.

This kind of earphones is placed inside the ear canal, and while being completely invisible to the outside, they are capable of transmitting and receiving sounds at an unlimited distance, thanks to a Bluetooth connection with a GSM Watch kit, that is, a normal watch which on the inside conceals a SIM card just like the one of your mobile phone, which allows for a completely invisible phone connection with a distant listener, who will be able to give real-time instructions, listening to what is happening around the watch and earpiece wearer, without others being aware.

In the field of surveillance and not only, using a micro earpiece can often make the difference between success and failure.

A miniature earpiece, thanks to its extremely small size, can easily be placed inside the ear canal of its user, and remain unnoticed even after a thorough body check or inspection. In spite of its tiny size, it is equipped with high level technology, which includes a miniature battery, an antenna and a small loudspeaker, in order to make sure that its user can receive information and instructions sent from a remote operator.

In a few words, we are talking about a micro sized FM receiver, which can be connected via Bluetooth to other devices such as for example a GSM watch, in order to create a complete system for discreet transmission and receiving, even at unlimited distance, since the GSM watch is equipped with a SIM card concealed inside, just like your every day mobile phone, and thanks to this card it can transmit the intelligence gathered, in real time and with a simple phone call.

Micro earpieces, furthermore, can be used to stay in constant communication with groups of people carrying out operations on a large area, such as workers on a construction site, rescue squads in large scale operations, and even with police agents during their struggle against crime, to avoid raising unnecessary attention while staying in touch.

Generally, a micro earpiece is equipped with a Zinc-Air type battery, with a very low energy consumption allowing for a power time ranging between 15 and 30 hours of operation. Furthermore, the earpiece can automatically switch to standby mode when it does not receive any communication for a certain amount of time, thus further reducing energy consumption while making it more difficult to detect for counter surveillance equipment.

Micro earpieces equipped with Bluetooth are now so small that they can easily be placed in their users’ ear canal, in order to guarantee invisible communication through any Bluetooth mobile phone or a radio.

A spy earphone is a passive type magnet, which receives the audio signal via a transceiver placed on a bracelet or a necklace, or simply hidden in the front pocket of your jacket.

Most of these earpieces are equipped with an equally small microphone, which can be concealed in the clothes you are wearing, in order to pick up the sounds around it and transmit them via radio to a distant listener.

The listener can be even on the other side of the world, if the earpiece and the microphone are teamed up with a GSM watch, that, is, a device which at a first sight looks like a normal watch (and works as such) but conceals a SIM card, just like the one of your ordinary cellphone, on the inside.

Thanks to the Bluetooth connection among different elements of the system, any sounds picked up by the hidden microphone can be transmitted via phone, and in the same fashion you can discreetly and invisibly receive information and instructions, directly on your earpiece.

Thanks to it, agents on a covert mission, police forces in an operation against crime, but even university students struggling with an exam, can stay in touch with a distant listener, who along with being able to hear in real time what goes on, will also be able to provide useful directions, information or news to achieve success of your operation, be it the hunt for a criminal or a tough exam.

When dealing with business negotiations, two of the key factors are confidentiality and velocity of circulation of the information within a closed circle of people, in order to make sure that decisions are made quickly and with a full knowledge of the contexts and situations. Sometimes though, one may happen to need to circulate this information even outside this closed circle of people, and this must be done in an extremely discreet way.

This is exactly what happened to one of our clients, a company operating in the corporate acquisitions field. During a decisive meeting for an international negotiation, the managers of the company needed to know the subject discussed in real time. The meeting, though, had been marked as extremely confidential, with no possibility of contact with the outside world, to make sure that no prying ears, especially from fierce competitors, could hear anything and somehow interfere.

At this point, technology comes into the picture: they asked for our advice, and the person who was going abroad to join this important meeting was equipped with a wireless spy earpiece, hidden inside his ear canal, and connected via Bluetooth to a GSM watch.

This watch contains a SIM card just like the one of a normal mobile phone, and an embedded microphone. Thanks to its Bluetoothwireless earpiece connection with the , this system makes it possible to communicate with a distant third party listener in any part of the world, by means of a simple telephone call towards the SIM card’s number.

Thanks to the Bluetooth connection between GSM Watch and its invisible earphone, the outgoing signal is transmitted via the phone line towards a distant listener, while the incoming signal (the voice of the distant person) is transmitted directly to the earpiece, thus enabling its user to transmit information and receive comments and instructions, in real time and in an absolutely discreet and invisible way, while the people around him are completely unaware of what is going on.

In short, for those who are sitting in their office, thousand miles away from the place of negotiation, it will be like being there, but without being noticed. This kind of solution can also be applicable in several other fields, like for example public political debates, when a technical or scientific subject is being discussed, and the deputy or congressman may not have a specific background in this field; therefore he may need a real-time specialized consulting from a remotely connected expert.

In the case we were following, the manager went to the meeting with his foreign counterparts, well equipped with his invisible earphonespy watch duly hidden inside his ears, and with a on his wrist. By gently pushing a button, he discreetly connected himself with his colleagues, several time zones away.

The negotiation went on for a few hours and was successfully brought to a conclusion, also thanks to the possibility of sending real time information to the head office, and of receiving instructions concerning the stand to be taken, thanks to their miniature spy earpiece. Of course, after a few hours of overseas phone conversation, the mobile phone bill was severely affected, but since the deal had been closed successfully, our clients were more than happy to pay it!

There are objects that just a few years ago we thought that could only be seen in action or spy movies, and that have become widespread, or at least much easier to find on the electronics market, at affordable prices.

An example of this kind can surely come from wireless earpieces, that we generally see used by secret agents on the big screen, but that can instead be used for a range of applications much broader than the mere exchange of information.

Certainly, in the security and surveillance field, for a detective or a police agent on a mission, and especially in the military for Special Forces members, it is absolutely vital to stay in constant touch with an operating center or a base camp without raising suspicions in criminals or enemies.

Some earpieces are connected, generally via Bluetooth, to a GSM watch with an embedded SIM card, thus creating a real listening and transmission system which can be used to transmit information at unlimited distance. The benefits of this kind of devices, as well as of radio connected earpieces, can be reaped by students at an exam, or workforce operating on large areas such as construction sites, mines, agricultural properties or when shooting movies on the outside.

In the movie business, the actors themselves, who may forget a line every now and then, may benefit from having a distant prompter while shooting an open air scene; and the good old prompter pit used in theatres may be obsolete thanks to this advanced solution.
A bit of the old romance of theatres would be lost, but the artist will have the chance to perform at their best and the audience can only be satisfied. As you can see, progress is running fast, and is available to everyone!
